Question

Two technicians are discussing replacing heater hoses. Technician A says that the replacement hoses should be the same length as the original hoses. Technician B says that the replacement hoses should be cut as short as possible to allow more coolant to flow through the heater core faster. Which technician is correct?
A. Technician A only
B. Technician B only
C. Both Technician A and B
D. Neither Technician A nor B

Answer 1

Answer:

A

Explanation:

In the given case, the replacing of heater hose is being discussed.

Technically technician A is correct and technician B is wrong. This is because the length of the heater hose cannot be shortened. If done so, there would be chances of busting of the hose because of the excess of heat developed in the hose. ( The heat transfer rate would decrease).

A. Technician A only
